Indoor allergens and pollutants hit their peak in the winter when homes are sealed against the cold. Follow these steps for healthier air.

Smoke Signals

Candles, cigarettes, and wood-burning fireplaces all release pollutants that worsen air quality and can even trigger health problems. To help keep your home's air clean, buy only nontoxic candles (such as unscented soy varieties), and don’t allow smoking indoors.

If you must use a fireplace, use cured or dried wood instead of pressure-treated wood, and have your chimney and flue inspected and cleaned regularly.
